Constant 100% CPU load for Windows 10 guest

Postby Cone » 18. Jan 2019, 08:53

My Windows 10 guest causes a constant 100% CPU load. The performance monitor is aware of the load, but not a single process seems to be causing it. I installed Windows 10 quite a while ago but hardly used it due to this problem, so there is hardly any software at all on this system. I have tried out a lot of things that didn't work:

* Updated VirtualBox
* Updated, re-installed, uninstalled guest additions
* Windows updates
* Changed a lot of virtual box settings (like chipset)
* Created a brand new VirtualBox configuration, only re-using the disk image
* Tried tweaking a lot of Window settings

Nothings seems to affect this problem in any way. My other Windows 7 guest is running without problems. The CPU load also doesn't seem to go down if you let the system run for a long time.

I am entirely out of ideas on this and I seem to be the only person on the internet with this problem. Does anyone still have an idea?

I don't see the processes being sorted by the CPU percentage; in the Resource Monitor you have the "Average CPU" to sort by, and I don't know what you have in the Task Manager. Sort them by CPU.

On my Win10, I usually see the updates and the .NET optimization as the usual culprits. It really punishes the CPU when there's nothing else going on...

@Cone: This sounds exactly like the problem that I have with my VBox. Would be so great if there was a solution to this.

With that amount of info provided your chance of a solution is 0% +/- 1%.

:lol:

"BerlinUser" has their own thread (High CPU on Win10 (1803) guest on Ubuntu 16.04), but I guess that's not enough, they have to dig into and wake up other threads as well... :roll:

socratis, perhaps you should change your username to Diogenes, because Socrates would have surely deduced that BerlinUser was commenting here solely to be helpful to Cone, and then would have chosen to remain silent instead of indulging in self-serving snark.
